Nie Y, Sun X, Cao R, et al. Drug Des Devel Ther. 2025(19): 971-980. Upon receiving the letter to the editor addressing the dosage error, we hereby correct the dosage from 3 μg/mL sufentanil mixture to 0.3 μg/mL sufentanil mixture for accuracy. In “Materials and Methods”, “Anesthesia Management” subsection on page 972, second sentence should read from “After placing an indwelling epidural catheter as a routine procedure, the mother was given an epidural injection of 0.1% ropivacaine and 3μg/mL sufentanil mixture”. To “After placing an indwelling epidural catheter as a routine procedure, the mother was given an epidural injection of 0.1% ropivacaine and 0.3μg/mL sufentanil mixture”. The authors apologize for this oversight.
